Hi I am wanting to build a device to allow me to lock up the torque convertor clutch in my transmission of my Toyota Prado overriding what the trans control is telling it to do to improve its performance while towing. I have built a basic circuit that just supplies 6 volts via a load resistor to the solenoid that controls the clutch however this is a rather harsh engagement of the clutch. I'd like to build something that will replicate the pulse width modulation that the vehicles control unit does but am a little out of my depth. Can anyone offer any advice.
If someone can do this I will post some snapshots off my oscilloscope of how the transmission control unit operates the solenoid.
